Electronic tension testing machine

Abstract

The invention discloses an electronic tension testing machine. The electronic tension testing machine comprises a bottom plate, an operation instrument plate and a bottom box, the bottom of the bottombox is fixedly connected with the top of the bottom plate, and the bottom of the operation instrument plate is fixedly connected with one side of the top of the bottom box. The invention relates to the technical field of the electronic tension testing machines. According to the electronic tension testing machine, tension of a plurality of similar test pieces can be simultaneously detected, tension value of the test pieces can be effectively detected by a tension sensor arranged at the top of an upper fixture and can be displayed on the operation instrument plate, so that a plurality of data can be compared and average value can be selected as a final data result, through such a comparative experiment, accuracy of the tension data of the test pieces can be increased, and detection efficiency is improved; and meanwhile, through the arrangement of first teeth and second teeth, the stress area of the test pieces in the clamping process can be increased, stability and firmness of clampingare strengthened, and good conditions for the follow-up testing work of the test pieces are created.

Description

technical field [0001] The invention relates to the technical field of electronic tensile testing machines, in particular to an electronic tensile testing machine. Background technique [0002] Electronic tensile machines are also called electronic tensile testing machines, also known as "universal tensile machines". Electronic tensile machines are classified from the performance of tensile machines: such as mechanical tensile machines and electronic tensile machines. More and more perfect, the tensile testing machine is suitable for plastic film, composite material, soft packaging material, plastic hose, adhesive, adhesive tape, self-adhesive, medical patch, protective film, release paper, combination cover, metal foil properties such as stretching, peeling, deformation, tearing, heat sealing, adhesion, puncture force, opening force, low-speed unwinding force and peeling force of products such as separators, backsheet materials, non-woven fabrics, rubber and paper fibers T...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an electronic tensile testing machine, which solves the problem that the contact area between the fixture on the testing machine and the test piece is small when it is clamped, so it is easy to fall off and affect the subsequent normal detection work. Simultaneously test The machine can only monitor a single test piece, which may cause inaccurate test results
